ICC analysis was used to assess the agreements for LV functional quantitative data between CSRT2CH_AL and SegSA_Simpson, and between CSRT4CH_AL and SegSA_Simpson in patients with NSR, and inter- and intra-observer agreements for LV functional quantitative data in patients with NSR and AF.

CSRT2CH_AL, area-length method using two-chamber compressed sensing real time cine; CSRT4CH_AL, area-length method using four-chamber compressed sensing real time cine; SegSA_Simpson, Simpson method using short axis segmented cine; EDV, end-diastolic volume; ESV, end-systolic volume; SV, stroke volume; EF, ejection fraction; LVM, left ventricular mass; NSR, normal sinus rhythm; AF, atrial fibrillation; LV, left ventricular; ICC, intraclass correlation coefficient; Inter, inter-observer; Intra, intra-observer.
